To o23 whom may; coi/wem:

Be it lmowri that l, flsreosltlrtsrrrz, s subject el' the Emperor of Austriafliimgery, and a resident of leudiiitworetllellbe, lohemis, lo tlie Empire of rlustrsilungery lieve invented e nei-vond useful lmprovement in Filters tor Bust-Suction .st pperetus, of which thetollowing is e full, clever, arid eireot` description.

My invention lies reference to (lust section epperetus or relates more pertieulrly to en improved iiiter 'f or the some..

The lllter consists ot en essemolege of cells, tlie mein walls ot which ore formed by line meel/led iebrlc, sind eellsleirig open' olterrien;` ly oppositeA sides, so tiret the tion sir to oe purified 'enters tlieveells which are open et the one'side and leaves, in puri lied condition, tlie oells which ere operi et theV opposite side. A device is also provided whereby the Y f. moment without its having to be removed from the apparatus. t

ln the accompanying drawing oneform of the invention is illustrateci applied to e suo tion apparatus. I'

Figure l is e, part sectional View or". apps retus with lter. F 2 is e' perspective View,

showing e number of iilter oeils assembled;

together. Fig. 3 illustrates by iront end end elevations the brushes employed for eleenisg the cells. j

The lust suetio apparatus' is ot temilisr construction, eonsistirig of the bellows o for seeking in tlieeir, provided with bock-pressure valves l). The bellows are protected by a sliell c, nioimtcfl-on e hollow losse d. 'lliese bellows ere' actuated by the craiilolismdleff, secured to the double-crsriked sliott e. The cover g of the shell c is perforated in the mers ner of s. sieve.

lo the hollow foot :or base d is pro'viclerl u lilterwessel or dust-chamber L, eonsisjtirigci e largelower part emi a. smaller to'iaert, which are detechebly conneeted and the iointrendered sir-tight l?? e rubber ln the top part of the vessel h there is located the filter, which consists ol en assemblage of frames each open et one side, These trames ere assembled parallel with each other, in vsuch manner tl'iet Vthe open side of the first iieme lies upws that of the next dov rlwerd, that of the t iird. again upward, tiret o? the'oirtll again ,ilowriwero7 ood so on altes v well lirlown construction enti ter een be olea-Heel et any' .top

mately upward emi tlownwertl. Between rsmes rie-mesliecl fabric ..76 is stretched' stoel seemed in suit-sole msmiemso that en eeseriiblege of cells is constituted, `open elter nately et the top enel bottom, the mein wells of the cells being formed by the fabric sheets- Between the 'uper Wall of the llc-(Fig. 2).v ilterwessel h and the filter, e filter-cloth t ie located in which :my dust stillfremainirlg in lthe air is de ositetl. The vessel 'h is een Heated with the bellows t by pipe 1', in .such manner that the oir in those cells which fire o'peri et the top can flow direct to the bellows..

lo order to admit of the fabric-'sheets if 'being 4cleaned. from adhering dust when neef' esssry, e system of bruslies m is emeoge nmedietely below the lter, being secu-reti to s rotary ber n, on -the one spindle-end or wliieh a handle o is mounted, outside the vessel h. lntlie drawing' (Fig.A l) iife brushes 'm are shown in operative position et the left-hand end. lot the ber n, while et the rightl1endend,for the sake of eleerness, only the axes; of the brushes are sliown. llli the position of rest the brushes point vertieelli dowmverds; when-it is required to sweep :1 kering. dust ofi the lfilter-shoe ts il?, vit is only necessary to turntlie handle o, when the s'erioiiig e. senii-circuler path. lo the loterior of the vessel i, just sfoove tile nipple o for-the flexible pipe, e, defleetor l is urriisliecl, so thetthe .coarse articles wlucli enter the Vessel. maybe fle ectefl downward to the bottom.

fr is a window,"for the purpose of enabling the height to which the dustlias accumulated inthe vessel to be checked'. vllflieo neces sexy, the Vessel een tlien be removed, opened and emptied.

The vessel h mit vbe (letselxebly seelrrecl im the losse (l by e e emp-rod i; iii edition to the serew-1i11t s Qn' tlie bellows afbeing worked, tlie dusty air entering the vessel 'k smtp, passes into' tlioselter oeils which @reopen below, flows through the lter-slieets g, the (lust being left behind, and thus puritiecl enters those cells whiclr'ere' operi shove, from which it Hows through the pipe Z irlto the bellows. Fromt'hese letter it is forced out through the valves b into tlie interior of the shell e, emi 'finally escapes into the atmosphere through the perforetioii in the oever g.

vlenti'o'n what brushes carrie .rticularly described my inclaim as new `and desire to Secnreby Lettersv Patent is Having now v1. A filter for dust suctiona'filaratns, com-I.

prising aniassemblage of para] frames open above and below alternately and having lter-sheets stretchedncross them; a 'receptacle, at the` top of which the frames are located, and havin anair-inlet belowand an air-outlet, above t `e frames; a .pluralit of Abrushes located below those frames w lch are open at the bottom;fand means for in` trducing the brushes into the same and withdrawing as described.

"2. A lter for dust suction apiaratus, coma` `iramesjand o erable from without; vand g "by the bar below those.

them therefrom; substantially.

of parallel frames open alternately and having, lter-sheets stretched across them; a receptacle, located in the said base, which the framesare located, and having an air-inlet belowl and an air-outlet above'the prisingl an assemblage at the top-of frames; and a` clamprod hinged tothe said base and ',taking over the top 'ofthe recep` .tacle, whereby the receptacle `is .firmly but detachably described.

4. A filter for dust suction afiaratusomprising an'assemblage of paral `e frames open held in thefbase; snbstantially'as 4o above. and below alternately and having filter-sheets stretched across them; a receptacle, vat the top of. which the frames are located, and having an air-inlet below and a tubulai` air-outlet abovethe frames; a bifurcated pipe' each portion constitutingr a suction member and means for creating suction therein alternately.; anda screw-nut uniting the same with the receptacle outlet substan tially as described..

In witness whereol` I have hereunto. signed my name this 15th day of January 1905, in 55 the presence of two subscribing-witnesses.
